I use a volume indicator, also programmed by an experienced Tradestation user, called Klinger + ATR. It is the finest leading indicator I am familiar with. I would be happy to provide the code to anyone who has the skills to write it for Metatrader or another platform. I only ask that it be shared with everyone, including me. It is NOT proprietary!
I trade only FUTURES now -- no more Forex. I like trading through an Exchange (CME, CBOT, etc.) because commissions are cheap (about $5 per round trip trade), spreads are tighter than most Forex brokers are willing to provide (usually 1-2 pips/ticks), and executions are accurate. The futures exchanges also provide GOOD, ACCURATE volume data. Forex volume data is spotty and unreliable, as others in this forum have indicated. I get no stolen stops. Many Forex traders are unaware that they can trade currencies through the futures market with superb liquidity on the majors and tight spreads. The charts are virtually indistinguishable from Forex.
Tradestation, as a broker, also offers Forex trading through Gain Capital. The spreads are MUCH tighter than you can get with a retail account with Gain. Spreads for the Euro and Yen are only .5 (yes, 1/2 pip) to 1 tick/pip. For the GBP, AUD, and CAD, they are usually about 2 ticks/pips. A tick in futures is the same as a PIP in Forex, but the values are slightly different.
